Asked by jonrid Sep 29, 2014 at 04:18 PM about the 1993 Mercury Topaz GS Sedan FWD

Question type: Maintenance & Repair

I get a tps (throttle positin sensor) code but the two screws are frozen in position.#3 and #4 Phillips screwdriver heads won't quite mesh.  Liquid wrench doesn't help. The sensor is made out of plastic. About the only way solutin I can see to replacing the sensor is using a dremil cut off disk to cut away the plastic so I can get a vice grip on the phillips head screws. Am I on the correct path?

That worked but it wasn't pretty. I still have the high idle 2000 RPM and a code 22.

WHOOPS I MEANT A TROUBLE CODE 12. I get the 22 also but I don't think that would cause the idle problem. There is an idle adjustment screw. Tried that but it has no effect.

    Need to replace clear center plastic part between the two headlights. It's a 1994 Mercury Topaz. Nobody seems to know. I believe the same styling was used on Ford's Taurus/Sable line-up. Thanks
